WebThe system output y ∈ ℝ 1 $$ y\in {\mathbb{R}}^1 $$ is the volumetric water content θ $$ \theta $$ (m 3 $$ {}^3 $$ /m 3 $$ {}^3 $$) at the rooting depth z r $$ {z}_r $$, which is an algebraic function of the state vector defined by the soil-water retention equation of van Genuchten . Equations and are used to generate all training datasets WebThe Theta model forecasts the future as a weighted combination of two Theta lines. This class supports combinations of models with two thetas: 0 and a user-specified choice (default 2). The forecasts are then. X ^ T + h T = θ − 1 …
